Hey guys, new to the forum but defiantly not to mustangs! Picked up a 2007 GTCS a month or so ago with a Roush m90 charger, Roush suspension, intake and exhaust. Just got it back from the shop after installing: 3:73FR gears, Killer Chiller, Smaller Pulley, Dyno Tune, and O/R X. Now waiting for my Borla Touring axle back to come in to replace the ridiculously loud Roush Extreme exhaust on there currently. Look forward to learning from everyone and just checking out the rides!
